My invention relates to an improved method of producing a germicidalrespirable gas such as gaseous ozonide.

The main object of my invention is to produce apparatus of highefliciency which is selfregulating, compact in form, and portable, andfurther to provide an improved method of commingling 'the constituentmaterials; to provide a removable, absorbent wick or the like; toprovide convenient means for holding the wick and for saving theby-product found on the wick; to provide an improved container for theheiniterpene or the like; and to provide in compact portable form meansfor drying the air admitted; means for forcing circulation of the driedair, and for the production of ozone from an air stream preferably dry.

One of the novel features of my invention is the method of comminglingthe hemiterpenes with the ozone, which comprises a wick or the like, thelower end of which is immersed in the liquid to be Vaporized, and theupper end forms an extensive surface saturated with the liquid overwhich surface ozone in a dry air stream is forced, the wick beingpositioned to form a clo-` sure between the vapor and the liquid in thereservoir. The wick is mounted on an open spiral form and isconveniently installed and removed. The used wicks are the source of avaluable pharmaceutical product, namely ozonated pinene pitch.

An illustrative embodiment of my invention is shown in the accompanyingdrawings, in which:

Figure 1 is a vertical section of the complete apparatus showing thehousing in dotted lines.

Fig. 2 is a vertical section with Vupper parts broken off showing anozone generator tube installed.

In the apparatus as shown in Fig. 1, a Wick l of absorbent material ispartially mounted on an open spiral forni 2. The lower end of the Wickis normally immersed in the pinene solution 3, and telescopes the innertubular portion 4 ci' the reservoir 5. lThe reservoir 5 has a fillingneck 6 provided with a stopper 7. The main neck of the reservoir 5 has aground taper face 8, which coacts with the opening 9 of the ball headl0, which is also provided with a side outlet ll.

The container or reservoir 5 is seated on a base section 12, which hasflanges 13 engaging the lower rim of the reservoir 5. The base section12 has an air inlet i4 and a hose connection 15. The air inlet isdirectly connected with a drier 16 containing calcium chloride or thelike. The

drier 16 has a gravity outlet l'l in the bottom, through which themoisture taken out by the calcium chloride is deposited in a receptacle18. The receptacle 18 has a screw cap 19 permitting the removal of theaccumulated water from the The elctric motor is which terminate aselectrodes inside the fan box 21. The current input leads 29-29 of thetransformer are connected to an electric receptacle 80. The electricreceptacle 30 is electrically connected With the electric motor 23 bywires not shown.

A convenient carrying case 3l or housing cover is shown in dotted lines.The removable carrying case is held in position by symmetrically placedflanges 32 and mounted on snap hinges 33. An alternative form is shownin Fig. 2, with the cover detached, and with the same numeralsindicating like parts.

Referring to Fig. 2, an ozone generating tube 34 occupies the centralportion in the base section 12 and the upper end of the ozone generatorprojects into the inner tubular portion 4, which forms a central airpassage through the fluid container 5. Between the ozone generator 34and the drier 16 is mounted an enclosed fan 35 driven by an electricmotor 35o. The conduit 20 con- 90 nects the drier l5 with the inlet tothe fan 35. Two delivery outlets 36 and 37 are provided from the fancasing. `The outlet 36 delivers air to the outside of the ozonegenerator 34. The outlet 37 delivers air to the center of the lowersection 12 95 and has an integral horizontal flange 38 upon which isfastened a block 39 having air passages 40. The upper surface of theblock 39 is shaped to form a seat for the ozone generator tube 34.

The ozone generating tube is constructed of two separate pieces. Thecentral portion 41 comprises a round glass tube having an etched innersurface and containing an electrode 42 which is fused in the wall of theglass tube. .The central electrode 42 is completely immersed in an elec-105 trolyte, and the tube is hermetically sealed. The electrode 42 iselectrically connected With one of the output leads 23 of thetransformer 27. The outside section 43 of the ozone generator 34 isshaped like an open top bell jar and provided with etched double walls.An electric lead 28, extending as an electrode, is fused in between thewalls and completely immersed in electrolyte. In sealing the sections 41and 43, enough free is left to take care of the expansion.

The spacing relation between the sections 41 and of the ozone generator34 is provided by the seat in the block 39 and spacers 44 which maintainclearance between sections 42 and 43 and the inside of the center airpassage through the reservoir.

In operation, the reservoir is lled with pinene or the like,substantially to the height of the iilling neck. A circular wick isslipped over an open spiral form which form enters the wick for aboutone-hair" its length. The other end of the wick is telescoped over theinner tubular portion of the reservoir until the spiral rests on the topof the inner tube. The spiral acts as a support for the upper portion ofthe wick and insures contact between the rising gases and the saturatedwick. The web of the open spiral alsoforms a neat and convenient way ofhandling the wick without touching the wick itself. After the wick hasbeen adjusted in correct operating position, the ball head is placed onthe taper ange of the reservoir. lThe air inlet tube is arranged to takeair from any desired source. Electric connection is made with theelectric receptacle 30 from any ordinary alternating current housecircuit. Since the electric motor and transformer are connected inparallel relation, both will operate. The .motor forces a current of airthrough the drier and delivers the dry air to the ozonizer connected tothe transformer terminals. In one case, Fig. 1, the ozone is produced inthe 'fan box, and in the other case, Fig. 2, the dry air is forcedthrough and around a special ozone generator, preferably sealedhermetically. In both cases the dry air and ozone are forced up throughthe cene tral passage in the reservoir, where commingling with pinenetakes place through intimate contact with the pinene saturated wick. Theswirling action of the currents of air and ozone in following thecontours of the open spiral produces the rapid formation of pinenevapor, and the chemical combination with the ozone forms an opticallyvisible pinene ozonized product. When the vapors pass out of the top ofthe wick into the ball, they are still in the presence of the outside ofthe wick, which is also saturated with pinene, Experience has proventhat the saturated wick is much more satisfactory and more efficient andeasier to handle and adjust than the evaporating tanks formerly used.When the wick method is used no definite level of pinene in thereservoir is necessarily maintained. The active surface of the wick issubstantially the same Whether the reservoir is full or nearly empty.

When the wick surface is once properly adjusted, no further regulationis necessary. This eliminates flow valves and by-passes as a part of theconstruction. A proper wick adjustment is made in the factory, and nofurther adjustment is required by the user. In operation, a by-productis obtained which is deposited on the wick. This by-product isconsidered a Valuable pharmaceutical product, and can easily be removed,since it is deposited on the wick. Since the wick forms a closurebetween the vapor and the reservoir, the use of the wick eliminates theannoying problern of frequently cleaning the usual evaporating tank.

Experience has proved the peculiar relations between the pinene andozone, in that ozone forms a chemical bond with the liquid pinene. Thechemical combination of ozone and vapor of pinene (two invisiblevapors), results in a visible product or" bluish-white appearance. Thisproduct, called vapor for convenience, is composed of myriads oi' solidsso minute and light as to float lazily in an ordinary atmosphere. Thesesolids are .separate and distinct molecules of the radical of theterpene group (C5Ha) after combination with ozone (O3). The ozone givesthe combined molecule its color and is held by chemical encapsulation,rendering the caustic properties of ozone not less potent but moreslug.- gish. iSzone, per se, a most powerful oxidizing agent, cannot beinhaled in strength. Its caustic properties are so severe, its action isimmediate and destructive in the presence of moisture such as providedby the surface or the respiratory tract, but when encapsulated in aterpene molecule the resultant product becomes not only visible butpleasantiy respirable, without destroying the caustic properties of theozone which may be available under conditions which provide a greaterdegree of chemical attraction, which is the condition when the combinedmolecule is 2 (Cel-ls) O3.

My invention comprises a pinene saturated wick o a predetermined lengthand body which provides a pick-up offer of pinene vapor to the ozone, inbasic form. The entire combining surface of the wick designed to beexposed to the action of the ozone, will always be in a saturatedcondition long'as any pinene remains in the container. rlhe creation orpresence or" the pinene vapor does not depend on the presence of an aircurrent. The ozone molecule supply predetermined to be of a certainquantity, will, at all times, come into contact with a sufficient numberof pinene molecules for absorption, and with these conditions xed, nofree ozone can be emitted from the top globe into the atmosphere to beinhaled.
